This invention relates to improvementsin saw sets,- more particularly of the class wherein the setting action is produced byl the blow of a hammerupon a set pin, and has for one of its objects to improve `the construction and increase the efficiency and utility'of devices of this character.

' Another object of the invention is to provide a simply constructed device of this character wherein provision ismade for adj Listing the anvil to increase or decrease the extent of the set Another object of the invention is to provide a device of this character having adjusting means whereby the device may be adapted to the size of theteeth Aof the` saw, so that the improved device may be employed without structural change upon saws having teeth of different sizes. n

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed 'out in the claims; and, in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is a side elevation, partly in section, of the improved device, Fig. 2 is an elevation from the feed end,`F ig. 3 is a plan view with the standard in section on the line 3-3 of Fig. 1, Fig. 4 is a transverse section on the line 4 4 of Fig. 3 looking in the direction of the arrow.

The improved device comprises a base or bed 10 from which a standard 11 arises, the base and standard being preferably cast in one piece and provided with lugs 12 by which the base and its standard may be secured to a bench or other support, if required. t

. The standard 11 is provided with a forwardly directed extension 18 yat its upper end, and with a bore 14 to receivea set pin 15. The bore 14 is counterbored at its upper end as shown at 16 and the set pin `15is provided with an enlarged head 17 which operates in the counterbore.l A spring 18 is disposed within the counterbore portion 16 and bears upwardly against the enlarged portion 17, and thus maintains the set pin yieldably in its upward position. The enlarged portion 17 'is provided with a ylongitudinal slot ;19,-and extending through the extension 13 fof the standard and likewise through the slot is a stop pin 2O4 the pinV operating to limit the movement of the set pin and its enlargedr head, while at the same time per- -mitting the downward movement of the same.

The base portion 10 is provided with a relatively large longitudinaly slot or opening 21',y having guide grooves or channels 224,23 inl its inner sides, and slidably disposed within the slot 10 4is an anvil carrying member 24, the member 24 being provided with ribsy25-e26 engaging in the guide channels 22-23. f By this means thefinember 24`is slidable within the slot 21 and is retained in position by theguide ribs. Bearing upon the upper fa`ce'.ofthe.1ne1nber 24 is a plate 27, preferably of hardened steel, and with one'end extending forwardly of the mem`- ber 24, as shown, and withfits terminal reduced. laterally as `shown at 28, the reduced portionl likewise having its upper face inclined, as shown. The reduced portion of the plate 27 forms the anvil of the improved device, and is locatedl directly beneath the set pin 15, the latter having its lower end inclined as shown at 29 to correspond to the required set of the teeth. Itk

a wing nut 32 upon its outer end to enable the screw` to be rotated, the portion 31 en gaging in a threaded aperture in the member 24 so that the lattermay be adjusted longitudinally ofthe base by rotating the screw 31 by its wing nut 32. By this means the position of the anvil portion 28 ofthe plate 27 maybe adjusted as required.l

Bearing aroundthe standard 11 is a U- shaped frame 33, the yforward ends of the member' 33 being provided with transverse saw relative to the set pin. The gage plates SLiit will be noted are in alinement transversely of the base l0 and are designed to control the position of the saw teeth, as hereinafter explained.

Mounted for rotation in the frame 33 at the rear side of the standard 11 is a screw 86 having a Wing nut 37, to enable the screw to be rotated, the screw being tapped into the standard as shown. By this means it Will be obvious that by rotating .the screw 36 by its wing nut 37, the frame 33 and its gage members maybe adjusted to correspond to the required yposition of the saw teeth relative to the anvil and set pin.

When the saw teeth are to be set the anvil 28 and the members 34E-35 are adjusted to correspond to the teeth of a saw, and the latter laid over the plate 27 With the lower side of the tooth Which it is desired to ,set located above the anvil 28 Vand With the points of the teeth against the gage members Bel-35. A blow `is then imparted to the enlarged head 17 ofthe setpin with the result of driving the set pin upon the saiv tooth and bending the same over the inclined upper face of the anvil, the set pin being immediately' returned to its. upper position by the action of the spring 18.V IThe saw-is then moved along kto bring another tooth into position` and the operation repeated.

The improved device is simple in construction, can be inexpensively manufactured and of any required strength and readily adapted without structural changes to sawy teeth' of varying sizes and forms. The plate QT being separate from the supporting member Q4 can be readily renewed When broken or impaired Without discarding the remaining portions of the device.

Vhatis claimed is A saw set comprising a base provided with a long slot opening through its for- Ward end, and having grooves in the inner facesdof its resultant furcations, a removable carriage slidably mounted between the furcations and having longitudinal ribs engaged inlthe grooves, a plate secured to the outer ends of the urcations and extending across thedspace there-between, an adjusting screw mounted in the plate'and engaged *with the .carriage to move the latter, adremovable anvil attached upon the carriage and extending beyond the inner end of the carriageto project over and rest upon the base, ,for the purpose of making a sound foundation for the saw teeth, means mounted `above the anvil for setting saw teeth with respect to the anvil head, and means for gagingthe edge of a saw With respect tothe setting means.

In testimony whereof, I affix my signature, in presence of tWo Witnesses.y l
